me in my room

You can render the shape of the stuff on desk (black on white background, rendering shadows of shapes would help as well), multiply resulting sequence with desk object sequence - render to separate file, and multiply with desk matte sequence - render to separate animation. Then proceed as I described above using resulting desk and matte and it should be fine.
[edit]
So far with this method I got this. And yes... Objects are hidden behind the desk ;) With additional matte you should work it out.

I'm just going to be REALLY lazy :P
I cut out the rest of the desk, including the little bit on the left side where the deskframe covers it. So now I should be able to just paste over the original and be done, no extra editing I hope. The only problem I can see is when the laptop opens it will show as soon as it passes the desk. I'll post this latest fix render, it's alpha, and the original as soon as it they are all finished rendering(only a few hours for the fix), so you can see what I'm talking about.
One thing I noticed is the light got dimmed in that process, any fixes for that? or should I just edit it out in GIMP before I merge them into AVI?
Correct me if I am wrong, but I think it would be useful to use the alpha channel to make the background of the fix render transparent, then overlay the fix over the original. I just do not know how to do this in the new programs. I'll read the manuals.
I found a good tutorial for wax that will help.

Make sure that your matte is mostly pure black and pure white (for solid objects in your scene), gray shades may cause darkening or lightening. You may also try different blending modes. In Wax I had a problems with opacity settings other than 100% for other than normal blending modes (I don't know if it was intended). Of course it should be fixable in postpro too...

I'm not sure about if it's available in Wax, especially without plugins or other workarounds. It should be possible if your overlaying movie is in 32 bit mode (24 bit for RGB and 8 for Alpha), but I'm not sure how to create one, at least I haven't tried that yet. Overlaying static or moving image would be easier because PNG with alpha or GIF would do the job.

Ok, I just quickly removed the lights in GIMP really quick, but I'll keep that in mind when I try out Wax more in other projects.

Hmm... Now I see that there are two different possible aproaches to this; having a background with holes cut out and the foreground moves behind it, or the foreground has transparent areas and floats over the background.
ADSohr:
I've figured out the process you described and I've followed it, but there are just too many places where it messes things up. I'm thinking that the only way I'm going to get everything to look exactly right is to just completely re-render the whole scene again. I could just render the parts where the laptop shows and delete all non-neccessary objects from the scene(entertainment center, bed, shelves), which would cut down the render time alot.
